MD5 & SHA Hash Generator
Generate MD5, SHA-1, SHA-256, SHA-384, and SHA-512 hashes from text, computed entirely in your browser.
Answer first
How do I use a MD5 SHA1 SHA256 hash generator?
Generate MD5, SHA-1, SHA-256, SHA-384, and SHA-512 hashes from text, computed entirely in your browser. Enter the known values and inspect the result immediately. For example, Hash the text abc to see MD5 900150983cd24fb0d6963f7d28e17f72 and SHA-256 ba7816bf8f01cfea414140de5dae2223b00361a396177a9cb410ff61f20015ad. Use the output to check your reasoning or shortlist a design, then verify the units, assumptions, and real-world limits that apply.
Hash results
—————Cryptographic Hash Functions
A hash function turns any input into a fixed-length fingerprint. The same input always produces the same hash, but there is no way to reverse a hash back into the original text, and changing even one character produces a completely different result.
MD5 and SHA-1 are broken for security use (collisions are practical) and are shown here for learning and legacy file-integrity checks only. Use SHA-256 or SHA-512 for anything security-sensitive, and never hash passwords without a dedicated password-hashing algorithm (bcrypt, scrypt, or Argon2).

Technical content reviewed
When this tool is useful
- Solving a MD5 SHA1 SHA256 hash generator task without repeating the arithmetic by hand
- Changing one input at a time to understand how it affects the result
What the result includes
- A result calculated from the values and units you enter
- A concrete reference case: Hash the text abc to see MD5 900150983cd24fb0d6963f7d28e17f72 and SHA-256 ba7816bf8f01cfea414140de5dae2223b00361a396177a9cb410ff61f20015ad.
What the model does not guarantee
- The result depends on the selected width, alphabet, encoding, and input format
- Encoding and number conversion do not provide encryption, authentication, or protection for sensitive data
Worked approach
Try a concrete set of values
Hash the text abc to see MD5 900150983cd24fb0d6963f7d28e17f72 and SHA-256 ba7816bf8f01cfea414140de5dae2223b00361a396177a9cb410ff61f20015ad. Change one input at a time, confirm the units, and compare the result with an independent calculation or relevant datasheet.
Common decisions
Questions engineers ask
What should I enter in the MD5 & SHA Hash Generator?
Use known values in the units shown beside each field. Keep every input within a realistic range and convert units before comparing the result with another source.
Can I use the MD5 & SHA Hash Generator result directly?
Encoding and number conversion do not provide encryption, authentication, or protection for sensitive data
How should I verify the MD5 & SHA Hash Generator result?
Repeat the worked example, check the units and assumptions, then compare the output with a second calculation, a trusted reference, or a measurement from the real system.
